Getting Started: Building Applications with RL-ARM

An HTML file that is intended to output a dynamically changing greeting

message to the web browser would look like this:

c a

The first two lines begin with the “t” script command. This means that the

remainder of the line is HTML and will be sent to the client browser. The third

line begins with the “c” script command. This means it is a command line. The

remainder of the line will be passed in an environment variable to the common

gateway interface function cgi_func(). The environment variable is called env

and from the example above it will contain the string “a <p>%s</p>”. The

start of this string consists of user defined control characters, in this case the “a”.

The cgi_func() must contain code to parse these characters and then format the

remainder of the HTML line.

U16 cgi_func (U8 *env, U8 *buf, U16 buflen, U32 *pcgi)

}

In the case above when the page is loaded, the “a” clause of the switch statement

will be executed. The sprint() statement then becomes

len = sprintf ((S8 *) buf, <p>%s</p> , "Hello World");

and the contents of buf becomes:

<p> Hello World </p>

which is then output to the browser.

To the browser the HTML code will appear as shown below.

<HTML><HEAD><TITLE>Hello World</TITLE></HEAD>

<BODY>

<H2 ALIGN=CENTER>Output a Greeting as Dynamic HTML</H2>

<p> Hello World </p>

</BODY>

switch (env [0])

}

return ((U16) len);

case 'a':

len = sprintf ((S8 *) buf, (const S8 *) &env [2], "Hello World");

break;

<HTML><HEAD><TITLE> Hello World Example </TITLE></HEAD>

<H2 ALIGN=CENTER> Output a Greeting as Dynamic HTML </H2>

</BODY>

</HTML>
